Summary of Changes

This release of cel-go (v0.32.0) introduces significant library expansions alongside a major infrastructure migration. Key highlights include the addition of native support for JWT and HMAC operations, Go-based JSON handling via NativeToValue, and robust timestamp parsing helpers.

Critical Upgrade: This release changes the module and import paths to cel.dev/cel-go. Users must update their import statements when upgrading to this version.

A variety of concurrency and stability fixes are also included, such as addressing nil pointer panics during native object traversals, and fixing cost observability when combined with state tracking or exhaustive eval

v0.31.0

Compare Source

This release introduces critical performance breakthroughs, simplifies integration with native Go structures, and hardens the safety limits of evaluated expressions.

Features

Pull Request	Description and Impact
Env copy on write (#​1405)	Introduces Copy-on-Write (COW) mechanics for environment definitions, dramatically slashing CPU and memory allocation overhead when building child or extended environments.
Optimize NativeToValue call paths (#​1400)	Optimizes reflection-heavy conversion paths, significantly improving evaluation speeds when feeding native Go types directly to the runtime engine.
Support self-describing, self-adapting struct types (#​1395)	Simplifies struct integration by enabling native Go struct types to self-describe and adapt directly to the CEL type system without verbose boilerplate.
Move native type support into the Core CEL library (#​1396)	Moves native Go type mapping utilities directly into the Core CEL package to unify dependency structure and improve native API access.
Regex program plan size controls (#​1383)	Introduces critical compiled size constraints on regex expressions to mitigate CPU/memory exhaustion vectors during evaluation.
Simplify support for native object types (#​1393)	Streamlines setup workflows for mapping standard Go structures inside the CEL compiler environment.
Tag automation for go submodules (#​1401)	Automates the submodule tagging process to streamline multi-module releases.

Fixes

Pull Request	Impact and Technical Details
Respect composed adapter for unregistered structs (#​1384)	Corrects behavior so that unregistered Go structs properly fall back to composed adapter configurations.
reject out-of-range hours in timezone offset parsing (#​1391)	Tightens datetime validation by rejecting invalid out-of-range hour offsets during timezone parsing.
Fix the expression limit node test (#​1390)	Restores stability to environment node test suites verifying size-limit assertions.
Correct documented default max value for lists.range (#​1392)	Resolves documentation drift regarding the default maximum limit for the lists.range function.

Breaking Changes

There are no breaking changes, but all ext.NativeTypes features are now available via cel.NativeTypes

Notes on Performance

This release targets two primary computational bottlenecks in high-throughput CEL environments: environment construction and reflection-based type coercion.

Expected Impact

1. Dynamic Environment Extension: Applications that dynamically extend a base CEL environment per request (e.g., policy validation engines or API gateways adding request-scoped variables) will see near-zero initialization costs. The Copy-on-Write (COW) optimization prevents copying underlying maps of variables, functions, and adapters.
2. Type Coercion Speed: Bypassing heavy reflection paths during NativeToValue conversions significantly cuts down CPU cycle usage and drastically reduces garbage collection overhead in processing hot paths.
3. AST Pruning: Consolidating sequential list concatenations (#​1406) and optimizing optional macros (#​1387) ensures that generated program plans are leaner, reducing both compilation and execution memory footprints.

High-Level Changes

• Enhanced JSON Interoperability: New support for JSON names across the checker, AST, and runtime allows for more seamless data handling when working with JSON-native structures.
• Improved Developer Tooling: Integration is now smoother thanks to new utilities for converting Go errors into cel.Issues and more descriptive, context-aware error messages.
• Greater Environment Flexibility: You can now redeclare variables as constants and export parse limit options, providing finer control over how CEL environments are configured and constrained.
• Native Struct Improvements: Support for mixing CEL and native values within native structs simplifies the handling of complex, hybrid data types.
